Basic and rich concepts on Simple interest and Compound interest

thumb_simple interest and compound interest trend  cover

Simple interest for a year is the percentage rate of interest applied on the initial amount invested and it is fixed year to year. On the other hand, Compound interest is the percentage rate of interest applied on the amount available at the beginning of the year, and not at the beginning of the investment period...

Basic and Rich Geometry Concepts Part 6, Proof of triangle area from medians

thumb_basic and rich geometry concepts part 6 area of triangle and medians proofs top

Medians are one of the most important set of elements related to a triangle. The symmetry associated with the medians give rise to a rich set of concepts and relations. In addition to a number of important area related concepts, we will discuss here how to find the area of a triangle from the given length of its medians...
